ASAH Technologies provides both ASAH Vehicle Gateway (AVG), the hardware installed in the vehicle, and CTC Intelligence, the software and service that uses AVG to collect eligible OBD data, submit qualifying Clean Truck Check results, and display fleet information in the customer portal.
The service is intended for qualifying OBD-equipped vehicles subject to California Clean Truck Check. CARB generally requires OBD testing for 2013-and-newer diesel engines and 2018-and-newer alternative-fuel engines. Vehicle weight, engine model year, fuel type, California operation, exemptions, and connector compatibility must be checked. Engine year is not always the same as vehicle model year. See CARB’s testing requirements.
Yes, for qualifying vehicles operating in California. Clean Truck Check can apply even when the vehicle is registered elsewhere, and the gateway can be shipped nationwide. This is a California compliance-testing service, not a nationwide substitute for state inspections.
A compatible pass-through or Y-cable may allow AVG and another device to remain connected. Compatibility is not universal. Confirm the diagnostic connector, existing equipment, and approved installation arrangement with the team first.
No. Vehicles must satisfy applicable testing and readiness requirements, and repairs may still be necessary. The service does not pay CARB fees, register vehicles in CTC-VIS, replace required opacity or visual inspections, or remove the vehicle owner’s responsibilities.
Most subject vehicles currently test twice a year. CARB states that OBD-equipped vehicles move to four tests a year beginning October 1, 2027, with qualifying agricultural vehicles and non-commercial motorhomes remaining on annual schedules. Use the deadlines shown in your CTC-VIS account. Check CARB’s current schedule.
